Tagan Turbojet 1100w Quad SLI PSU

Testing

Load Testing

In order for the results from all current and future PSU reviews to remain fair and comparable, Overclock3D uses a custom built Power Supply load stress tester.

The tester will be placing the following loads on each of the Turbojet 1.1kw's rails:

+3.3v - 20a Load
+5.0v - 20a Load
+12v1 - 15a Load
+12v2 - 15a Load
+12v3 - 15a Load
+12v4 - 15a Load

The results are collected from a Mastech MAS-345 Multimeter which logs its readings via RS232 to a PC.

Tagan Turbojet +3.3v Tagan Turbojet +5v

Both the +3.3v and +5v rails managed to maintain excellent rail stability with less than 1% fluctuation. Both rails were well within ATX specification and these results place the Turbojet amongst some of the best PSU's we've tested here at OC3D.

Tagan Turbojet +12v1 Tagan Turbojet +12v2

Tagan Turbojet +12v3 Tagan Turbojet +12v4

Yet again the Tagan impresses us with its excellent voltage regulation, this time managing to keep fluctuation on all of the +12v rails at or below 0.5%.


Efficiency Testing

Efficiency tests are performed by measuring the wattage consumed by the power supply at the mains against the power (in watts) consumed by the OC3D power supply stress tester.

The results may not be as accurate as those produced by professional testing equipment, but will certainly come in handy when comparing several power supplies against each other.

Tagan Turbojet Efficiency

The Tagan Turbojet was placed under a load of 886 watts. This counts for a total of 80% of the power supplies rated output. At this load, the power supply required 1072 watts from the mains to produce the 886 watts required by our custom made power supply tester. Therefore the efficiency of this power supply can be found by a simple equation: (886 / 1072) * 100 that works out to be an efficiency rating of 82.6%.


Noise Testing

At present Overclock3D doesn't have the professional equipment required to reliably measure the noise output of devices. However, as a new part of our testing procedure we will be recording the PSU at idle and load so that you can make your own judgments. All recordings are taken at 30cm distance from the unit.

Fan Increase Recording - Download
Load Recording - Download

Before you go away with the wrong impression from these recordings I'd like to remind you all that these recordings were taken outside of a PC case. As a result the PSU is actually quite a bit noisier in these recordings than it is in real life.

As stated earlier in the review, the Turbojet utilised two 80mm fans. The one closest to the back of your case is designed for silence, whereas the fan located inside your case is designed for performance. As a result the noise from the high-cfm performance fan is dampened by your case enclosure, and the majority of audible noise from the unit comes from the more silent Globe Fan.

Tagan have also impemented a fan speed controller that adjusts the rpm of the fans based on the PSU load. This works quite well, but you can expect the fans to be running at 100% once the PSU gets to around 75% load. You can hear the fan speed increase in the recording above.

For those of us looking for a silent PSU to go inside their HTPC system the Turbojet may not be ideal, however it is highly unlikely that a silent/HTPC system would ever need a whole 1.1kw of power. People utilising a Quad-SLI high-end system are likely to be accustomed to noise, and for these people the Turbojet's noise levels should be reasonably acceptable.

"With power consumption of graphics cards on the rise, more and more PSU manufacturers are releasing 1000w+ units. Today we take a look at Tagans latest model, the Turbojet 1.1kw."

Beastly PSU. I freakin LOVE topower shielding/sleeving. It's the sickest looking thing ever. Those round heatsinks are sick, too.

That PSU looks intense, I don't need something with that much power but it is still extremely sweet. Nice review

200 for that i would definitly pay.

comes in at over 320 over here.
